Re: Communication module
One of the reasons for all this is to gather pieces for the future board which has to be our own board for the reasons of price & size. Then I say definitely bluetooth. After it gets it's final resting spot it'll be nice to get data wireless. I'd also suggest using USART1 or USART3 then you can...

Re: Connectivity overview & build-in commands
Oh, by the way by default we use USART3. TX is pin PC10 & RX is PC11 For the 'human readable' part would you be interested in more of a 'live console' approach? I've dug through the console function and figured out how to bind to arrow keys and the like. It'd be something similar to: http://www...

Re: rusEfi console
It's been too long since I've looked at Java.
Any chance you could add a scrolling graph?

Workspaces & Tool Chains
I thought it might be good to have a thread with what everyone is using. IDE: ChibiStudio OS: Windows 7 x64. Toolchain: Pre-built GNU toolchain from ARM Cortex-M & Cortex-R processors (Cortex-M0/M0+/M3/M4, Cortex-R4/R5/R7). Once I get my workflow defined I'll post instructions. I have been using...

Re: Making Diesel Controller
When does the GDI do injection? Is it near TDC like diesel engines? Another thing is that gasoline will evaporate in air, diesel will just pool. You need to atomize the diesel fuel so you get it to a very high pressure so that at the injectors it atomizes. But that's more of a thermodynamic discussi...

Re: Making Diesel Controller
I think you are flipping PSI and bar. Nope. That's a gasoline engine. I'm talking about Diesel common rail engines where you need complete atomization near TDC. On diesel engines, it features a high-pressure (over 1,000 bar or 100 MPa; 15,000 psi) fuel rail feeding individual solenoid valves, as op...

Re: Making Diesel Controller
See item 35320B for the mechanically driven fuel pump $582, and 35310 the injector for $66. There is pipe connected to 4 injectors, so common rail. What I don't know for sure is the pressure. I believe it's around 100 bar, but don't know for sure. I wonder if the driving would be the same as a piez...

Re: Making Diesel Controller
I'm more of a hardware guy, who can read code, but can't generate it very well. Good. I'm an ME that can code so I have the other half of the spectrum covered. Here's some documents I found on driving a Piezo. Lots of graphs that will probably make more sense to you: http://www.dspace.com/files/pdf...

Re: naive question on dev board power consumption
So at 40 mA I will drain a 60 AH battery in 1500 hours, that's 62 days. I guess that not really an options :( Thanks for reminding be about these RTC boards, I've seen them before - I guess that would be the way to go. Based on the presentation I found the STM4F should have a low power option for j...

Re: Thermocouple input?
1700 C is an extreme case. I believe MY turbo starts melting at 750-800. Depending on the turbo.
The thing about EGT thermocouples is that they are very cheap as sometimes they have a short lifespan where they live.

Re: Thermocouple input?
Most newer wideband O2 sensors(heated) also have a temperature output, or at least provide enough data for you to be able to derive a temperature from it. I don't know what kind of accuracy you need out of an EGT sensor in a turbo application, I'm not a turbo guy, but I know the stock O2 in my dail...

Right now I have a STM32F4-Discovery board with blinking lights in front of me. Once I get both my cars up and running I plan on dismantling my old injection pump and start playing with that on the bench to see what type of PWM signal it likes. Then figure out how the hall effect sensor reads and th...
